From what I've gathered, the two are Chinese women.
The cosplayer portraying 2B is a streamer who's account name is "Devil Porter", according to Google Translate's Mandarin/Cantonese/Ching Chong Bing Bong. Here is the link I've used to present my findings: http://www.acfun.cn/v/ac3646281
However, I there's a possibility of the Devil Porter account being a fan that archives the livestream, but my investigation seems to support my claim. Here's the link: http://www.acfun.cn/u/363686.aspx#page=1 . As for the cosplayer portraying 9S, I cannot find much on her. Searching the video's description of "9S:言生" only brings up Weibo links, which I cannot access for some reason. Must be Chink internet censorship.
I hope I helped and provided enough autism to remind you that you're most likely better off than me.
